Obesity Clinical Trial - Energy -Sensing Metabolites in Caloric

Status Completed

Clinical Trial Summary

General integrated goal of the coordinated project: To elucidate the role of succinate and other metabolites derived from the intestinal microbiota such as Short Chain Fatty Acids (SCFAs), as energy sensing metabolites in the context of obesity and type 2 diabetes (T2D). Specific objectives of Subproject 1 (SP1): 1a. - To investigate whether intermittent fasting (IF) is better than Continued Daily Caloric Restriction (DCR) in terms of metabolic improvement through the study of: 1) the dynamics of gastrointestinal hormones and energy sensing metabolites, 2) the intestinal microbiome, 3) variability on succinate and SCFAs, MCFAs and Biliary Acid after weight loss; Methodology: clinical study: randomized, cross-over design, study participants (n=15) will consume either lifestyle recommendations for a healthy Mediterranean diet under a continued caloric restriction diet (DCR) or will undertake an intermittent (IF) protocol. Clinical, anthropometrical and functional studies. Metabolomics for gut derived metabolites in plasma. Enteroendocrine gastrointestinal dynamics. Metagenomic analysis.

Clinical Trial Description

To investigate whether IF is better than DCR in terms of metabolic improvement through the study of: 1. the dynamics of gastrointestinal hormones and energy sensing metabolites 2. the intestinal microbiome 3. variability on succinate and SCFAs MCFAs and BA after weight loss Human study protocol: A pilot clinical trial in human study participants will be assayed. Participants for intermittent fasting (IF) will be asked to fast for 24 hours on two days of the week (2/5 protocol). 1A.-Design: Utilizing a randomized, cross-over design, study participants (n=15) will consume either lifestyle recommendations for a healthy Mediterranean diet under a continued daily caloric restriction diet (DCR) or will undertake an intermittent (IF) protocol. Each study period will be 8 weeks - total study period will be 16 weeks + a 4-week washout period between dietary exposures. The study participants will be adults who have obesity with a Body Mass Index (BMI)25 kg/m2 and 40 kg/m2 and have no contraindications for intermittent fasting (see inclusion and exclusion criteria below). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
